As a french who live in Paris, I find that comment extremely strange. For two reasons :
* first, fowl is very common in french food (not turkey usually - chicken, duck, and goose most often). And the fowl in the set is any generic fowl as far as I know. The size isn't even that big for a goose, pr some specifics kind of chicken.
* second, snails, oysters, and the like may be iconic but aren't very common. Both because it's not too popular (I think about 1/3 of french actually want to eat snail), not too common on actual restaurants, and not a specific sign of high class food (it's wine the main marker). I also think a specific mold for cooked snails and oister would be very hard to do given the small size.
Also, the crampedness is quite typical of Paris actually. Well, I guess they could have added two more story, but the actual appartment and restaurant size are a pretty good representation of my experience.
For a Paris restaurant, the main addition one could make is a cellar. Not for the wine, but because a lot of restaurant use their cellar to have more room for customer. Of course, making a set with a cellar have a lot of complication, including not having the same base level as other modular.
